Answer 1

Answer:

10. Denominator should be: 87

=18/29×3/3= 54/87

Ans. 54/87

11. 2/3,-4/9,-8/11 ( First:Make all the denominators positive but

In This Case it's not required )

=2/3×33/33,-4/9×11/11,-8/11×9/9 (Second:We need to make all denom. same by finding lcm i.e 99 is the lcm of 3,9,11 )

=66/99,-44/99,-72/99 (Since -72<-44<66)

= -8/11<-4/9<2/3

Ans. -8/11<-4/9<2/3
